AIR CLEANSING AND COOLING DEVICE.

SPECIFICATION forming part of Letters Patent NOQ701,074=, dated May 27,1902. Application filed February 5, 1900. Serial No. 4,001. (No model.)

in the art to which it appertains to make and use the same.

This invention relates to a new and useful improvement in air cleansingand cooling devices; and it consists in the construction hereinafterdescribed.

In the annexed drawings, Figure 1 represents a vertical longitudinalsection of the device. Fig. 2 represents a horizontal transverse sectionof the device onthe line 2 2, Fig. 1. Fig. 3 represents a verticaltransverse section of the device on the line 3 8, Fig. 1.

In the drawings the letter A represents a suitable case having at onecorner of its top the air-inlet a and at one side substantially diagonalfrom the inlet Ct an air-outlet a. Extending across and inside of thecase A at its top and near the air-inlet a is a pipe B, having atitsbottom the perforations b. This pipe is for the admission of water orsteam. At the bottom of the case A there is a drainpipe C, communicatingwith the interior of the case Aat its bottom at the point 0. Theinterior of the bottom a of the case A is inclined, as shown at a a",the incline sloping downward to the point 0. As shown, the outlet ordrain pipe communicates with the interior of the case A near one side(the side opposite to the air-outlet a) and substantially under theair-inlet a.

Extending from the side ce of the case A, near the top a of the case andimmediately under the air-inlet a and the pipe B, is a shelf orbaffle-plate D. This bathe-plate is secured by a close joint with theside a and the ends a of the case A. This baffle-plate D slantsdownwardly from the side a, but does not extend over to the side a ofthe case A, there being a space a between the side a of the case A andthe end 61 of the battle-plate D. This end (Z of the baftle-plate D isturned upward, so as to have a vertical portion (2,

and then backward, so as to have a lip (P. This construction forms a,recess or channel at the lower end of the baffle-plate D. In the bottomd of the baffle-plate D just within the channel d there are made anumber of holes d extending across the bottom of the baffle-plate D.Below the battle D is another baffie-plate E. This baffle-plate issecured to the side a and the ends C66 of the case A, ex-

tendingdownwardly from the side a and stopping short of the side a therebeing a space a between the side a of the case A and the end 8 of thebaffle-plate E. This baffle-plate E has substantially the shape showninthe drawingsthat is, with the two downwardly-slanting portions 6 e andhorizontal portions 6 and c baffle-plate E is turned upward, so as tohave a vertical portion 6 and then backward, so as to have a lip 8 Thisconstruction forms a recess or channel 6 at the lower end of thebaffle-plate E. At each end of this channel 6 there is an opening at theends of the case A. These openings e communicate with down-pipes F, theupper endsfof which are at the openings 6 and their lower endsf'terminate just above the bottom of the case A. These down-pipes ordrains F may be constructed so that the ends a of the case A may formone side thereof.

Extending from and connected with the under side of the baflie-plate Edown to the bottom of the case A and connected therewith are series ofstaggered separators G, made substantially \I-shaped in cross-section,their substantially concaved faces being toward the side a of the caseA. Between the last of these separators G and the air-outlet a is placeda diaphragm II, which extends slantingly inward and upward from near thebottom of the case A and secured by close joint to the ends a of thecase A. This diaphragm H has perforations 72, which lead from the pocketK behind the diaphragm out into the interior of the case A. At asuitable distance below the bottom or under side of the bafiieplate Ethe diaphragm H terminates in a lip h, which extends entirely across thecase A from side to side and is turned downwardly, so as to form anoverhanging lip. Between this lip h of the diaphragm II and thebaffleplate E is a space forming a passage-way I.

The end 6 of the' At each end of this passage-way, secured to the insideof the ends a and extending from the under side of the baffle-plate E tothe lip h, are cleats or plates h, which-extend backwardly away from thesides a, being-substantially in construction like the lip it, this lipand the two plates h forming a diverging the bafile-plate D the water inthe form of spray is broken up into fine particles, and the air andwater are thoroughly com mingled, the airbeing cooled and at the same time cleansed, particles of dirt, &c., in the air being forced therefromby the water and with the water fall upon the bathe-plate D. The air,with some portions of the sprayed water, passes over the top of the endd of the baffle-plate D and down through the passage a to thebaflie-plate E. The water with the dirt passes down the baffle-plate Dand through the holes d falling upon the baffle-plate E and running downthe same into the channel 6', and down'through the opening e and throughthe down-pipes or drains F to the bottom of the case A. As the air witha portion of the sprayed water passes down over. the baffleplate E aportion of the Water is precipitated upon the baffle-plate E and alsopasses down into the channel 6 and out through the drains F. The airthus divested of most of the water passes amid the separators G, whereatany remaining particles of moisture should be separated from the air,and the air then passes through the passage-way I to the airoutlet a.Should any moisture'get through the separators G, the diaphragm H andthe overhanging lip h with the plates h would arrest the same, or shouldany water pass through the passage-way I it will collect in the pocket Kand run through the perforation 7L2 into the interior of the case A.

While the device thus described may be employed anywhere where it isdesired to cleanse and cool air, still it is more specially intended tobe used upon moving structures, such as cars or vessels, wherein thewater would be thrown about within the case. The construction herein setforth tends to prevent the motion of the Water from throwing it up, sothat after having once been separated from the air it should be againcommingled therewith and passed off to the blower. It will be seen froman inspection of the drawings that the entire construction tends to keepthe water at the bottom of the case after it has once reached it; butmore especially it is designed by the use of the inclined diaphragm Hand steam or hot water maybe admitted throughthe pipe B.

In my Patent No. 586,365 is shown a device provided With a topbaflie-plate, over the straight lower edge of which the water flows in asheet, and abottom baffle-plate provided with a closed end or trough,into which the water collects and flows through a down-pipe. In myPatent No. 631,377 isshow'n a device having a number of baffle-plateseach provided with riffies having perforations in them. In this devicethese riffies are straight, and no one of them has its top turnedbackward, so as to form a channel, recess, or trough; also, theperforations are in the riflies and not in the bafiie-plate. Hence thewater at the last riffle of the top baffle-plate not only flows over thetop of such riflie, but also passes through the perforations in a sheetover the edge of the baffle-plate. In the present device the holes orperforations d are in the baffle-plate D in a line across its bottom.Hence the water collects inthe recess, channel, or trough at the lowerend of the baiileplate and runs vertically downward-through the holes (1in a sheet of water which sprays at the bottom.

Having described my invention, what I claim is The case A having the airand water inlet and outlet, the baffle-plate D having at its lower endthe vertical portion d, the backward portion (1 forming the recess,channel I JOSEPH MCCREERY,
